ABSTRACT

This paper investigates the relationship between monthly solar flux cycle (28 days) and hurricane intensity. The intent of this investigation was to determine whether a relationship exists between hurricane intensity and the monthly solar flux cycle. For the purposes of this investigation the F10.7 centimeter (2800 MHz) solar flux was plotted against the life cycle of several hurricane events. The results of this investigation are discussed in this paper.

The investigation and discussion of results focus on the plot of the F10.7cm flux versus the life cycle and lowest pressure for each storm. These preliminary results identify (1) whether a relationship between hurricane intensity and solar flux exists, (2) the nature of the relationship, (3) possible structure for future formal studies, and (4) the potential for predictive uses. A presentation of the results includes the simultaneous plot of hurricane intensities and the F10.7cm flux data. In addition, visual graphics are included for a subset of hurricanes to show the structure associated with the more intense storms used for the study.
